VB said:
I did. Sounds like this could have something to do with it. I will search
for an image like this. If I find it, how do I "embed" it? What's the
explaination behind why Outlook is doing this?
Anti spam, images are often urls like
[email protected].
When the client opens the mailmessage the image loads and the spammer
knows that (e-mail address removed) is active so you can expect more
spam 'cause he will probably sell your mailaddress as proven being active.
How to embed?
Insert (not attach) a image in your mail and check out that
construction, it will look like (removed all other stuff):
[... snip some headers ...]
Content-Type: multipart/alternative; boundary="#SEPERATOR2#"
Content-Transfer-Encoding: quoted-printable
[... snip more headers ...]
--#SEPERATOR2#
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: quoted-printable
Your email client does not support HTML messages
--#SEPERATOR2#
Content-Type: multipart/related; boundary="#SEPERATOR3#"
Content-Transfer-Encoding: quoted-printable
